STOVE FDR 'RAI LWAY -CARS.

SPECIFICATION forming part of Letters Patent No. 377.057, dated January 31, 1888.

Application filed A pril 2, 1687. Serial No. 233.345. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES Bassnvr, of Newark, Essex county, New Jersey, have invented a new and useful Improvement in Car- Heating Stoves, of which the following is a specification.

Hy invention relates to a stove for warming railway-cars. Its principle is the automatic inclosnre of the fire-pot and contained fire in a tight casing or envelope whenever the car is subjected to violent jar or concussion, or when thrown over sidewise, or when the stove is displaced or shattered, as in the event of collision, derailment, or other similar accident.

My object is to prevent the wood-work or other inflammable material in the vicinity of the stove from becoming ignited in case of casualty, as aforesaid. The casing is of metal or other suitable fire-proof material strong enough not to be injured or broken even if the car is wholly destroyed. Although the fire becomes hermetically sealed in this envelope the latter does not become hot enough to set fire to adjacent wood-work, &c., and, more over, the fire becomes soon extinguished by reason of the exclusion of air and the confinement of the carbonic-acid gas generated.

In the accompanying drawings my invention is shown applied to a stove of simple construction.

Figure 1 is an elevation, with a portion of the shell of the stove broken away to show the hood or fire-pot cover suspended therein. In this view the doors 9' and t are shown as closed and the ehutel outside the casing. Fig. 2 is a vertical section on the line 00 a of Fig. 1. In this view the doors j and i are shown as open, the chute Z being inside the casing. Fig. 3 is a partial horizontal section on the line y y of Fig. 1, showing the arrangement of the door and attached chute. Fig. 4 is a detail of the releasing device for the hood.

Similar letters of reference indicate like parts. 7

A is the fire-pot, which may be an iron castinglined, if desired,with firebriek in the usual way.

15 is the grate. The lirepot is here shown as cylindrical in form, open above the firechamber 0 and closed below the ash-pit D. It is attached in any suitable way to the heavy base-piece E of the stove. This base-piece has an upwardly-projecting annular flange, F, between which and the fire-pot A there is an annular channel, G. In the fire-pot A, and affording communication with the ash-pit D, is an opening, H.

The shell or casing I of the stove is supported upon the base-piece E, and may be secured to the outer periphery of the flange F. Said shell is surmounted by a cover, J, which may be of cast metal. The central portion of said cover is of conical form, surmounted by an open ring or short cylinder, K. To said ring the usual draft-pipe, L, is secured in any suitable way. Extending across the ring K is a shaft, M, which is free to turn in the sides of said ring. To the middle of said shaft is secured a hook, N. Suspended from said hook N by the chain 0 is the hood P. This hood is in the form of a hollow cylinder open beneath and provided at its lower extremity with a flange, Q, having a rounded edge, as shown. This cylinder may be an iron casting. On its outer periphery are lugs R, which receive the guiderods S, which are secured inside the stove-shell in any suitable way.

It will be noticed that the hood P is suspended dircctly over the fire-pot A, but at such a distance therefrom as not to impede the draft. The products of combustion circulate around the outside of the hood in passing to the escape-pipe.

To one end of the shaft M, outside the ring K, is secured a lever-arm, T. On the end of this arm is a projection, U, which extends downwardly and then laterally, as shown in Fig. 4. Upon the cover Jis cast or otherwise secured an arm, V, which supports the socketbearing W.

a is a rod, having at its upperend a projection, I), as shown in Fig. 4. This projectionb engages with the projection U. Upon said rod is a ball, 0, which rests in the socket W. Said rod then passes through said bearing and its lower portion is threaded. Upon said rod is an adjustable weight, d, which is supported by a nut, 6, received upon the threaded portion of rod a. The opening in the socket W is flared at its lower edge, so as to allow of considerable swing to the weightd as a pendulum. The length of the lever-arm V and the weight d should be such that the weight will over balance the hood I, so that the latter will nor rounded edges 9 of the latch-dogs.

mally remain suspended from the hook N on shaft M. The ball 0 then rests in the socket W and the projection. b on rod 11 engages with projection U. Suppose, now, that, this stove being in the usual position of the heater in a railway-car, a collision or otheraccident occurs. If the shock is violent enough to throw the car over sidewise, or even to give it a heavy jar, the tendency of the pendulum-weight to remain Vertical will infallibly cause a disengagement of the projection U and the rod a. The instant this happens the shaft M is free to turn, the lever-arm T rises, (see dotted lines, Fig. 2,) and the hood P drops. As the hood is directly over thefire-pot, A, and, moreover, is guided in its descent by the lugs R and the guide-rods S, it lands directly upon said.fire-pot, with its lower flange, Q, in the annular channel G. The fire-pot A is now completely enveloped in metal, and of course no fire can escape.

In order to hold the hood P in place after the descent, I arrange in the flangeF of the base-piece E spring-latches, one of which is shown at f, Fig. 2. The dogs of these latches have upper rounded edges, 9. The rounded edges of the flange Q of the hood P meet the The dogs are thus pushed back while the flange Q is passing them, and finally the dogs spring back over the rim of the flange, as shown in Fig. 2. The latches may be disengaged by withdrawing the dogs by means of the rods attached thereto, said rods terminating in rings, as h, which may be outside the stove-shell. It will now be apparent that, even if all ,the lighter portions of the stove are destroyed, no matter how suddenly, the fall of the hood P is even the more certain to take place. Then the hood, fire-pot, and base-piece become substantially a single mass of metal. The fire is shut up therein with all access of air or possibility of egress of carbonic acid cut off, so that it speedilybecomes smothered.

There are of course other devices which may be adopted forreleasing the hood P and allowingit to drop in event of sudden jar, &c., and I thereforeldo not limit myself to the particular arrangement for that purpose'here shown. My present device, however, I consider preferable. The are of swing of the pendulumweight d may be adjusted by raising or lowering said weight upon rod a by suitably moving the nut e,'and the sensitiveness of the contrivance may thus be controlled. -It will of course be understood that the ball and socket shown constitute a universal j oint,and that the shoulder b on rod or is causedto move off of the projection U through the inertia of the weight when the stove is inclined beyond a certain point, or when a violent jar occurs.

i is the feed-door, and j the door affording access to the ash-pit. These doors are of the usual form and construction,and are hinged to frames kk, attached to the stove-shell. Hinged to the opposite side of the frame It is a chute, l, which is simply a square frame of plate metal having a depth equal to the distance between the dooropening. The inner edge ofsaid frame, which meets the periphery of the firepot,is rounded,so as to fit closely thereon. The

chute Z is connected to doorj byjointed linkrods n 0, so that when the door is closed the chute is thrown back in the position shown in Fig. 1 and marked 1 in Fig. 3. NVhen the door stands at right angles to the opening, as indicated in the position marked 2, (dotted lines,) Fig. 3, the chute stands parallel to the door. When the door is thrown back,as shown in the position marked 3, (dotted lines,) Fig. 3, the chute enters the door-opening and meets the fire-pot. The object of this construe 'tion is to prevent coal when the fire is being scent, as all these parts may be varied in form andin general arrangement.

I claim- 1. In a stove, the combination of an open vessel for containing the fire, a hood detachably suspended and adapted to fit over said vessel, a suspension-hook for said hood, a pivoted lever connected to said hook, and a detachable weight suspended from said lever and counterbalancing said hood, substantially as described.
